  The present invention relates to an elevating parking apparatus that uses a pallet.

FIG. 1 is a configuration diagram of a conventional elevator-type mechanical parking apparatus.
In this figure, 1 is a vehicle, 2 is a pallet, 3 is a vehicle storage shelf, 4 is a cage, and 5 is a hoistway.

The vehicle 1 is, for example, an ordinary passenger car, and use of a large vehicle or the like is restricted depending on the standard of the parking device. The pallet 2 is set to a size suitable for the vehicle 1 and is configured to move with the vehicle 1 mounted thereon. The vehicle storage shelf 3 is a shelf for storing the pallet 2 on which the vehicle 1 is mounted or the pallet 2 in a state where the vehicle 1 is not mounted. In this example, both sides of a hoistway 5 described later (in FIG. ).
The cage 4 is a so-called lift, and moves the vehicle 1 mounted on the pallet 2 by moving up and down between the boarding floor and the vehicle storage shelf 3 that stores the vehicle 1. For example, the cage 4 may be suspended from an upper floor (not shown) by a wire or a chain.

  The elevator-type mechanical parking device described above, after entering the vehicle 1 on the empty pallet 2 at the entrance / exit at the entrance floor (the ground floor in the figure), the driver leaves the room, The cage 4 is raised, stopped at the position of the vehicle storage shelf 3 without the pallet 2, the pallet 2 on which the vehicle 1 is placed is traversed, and the pallet 2 is stored in the vehicle storage shelf 3.

Japanese Patent No. 3449669

In the pallet traversing apparatus in the parking apparatus as described above, when another pallet 2b is mounted on the pallet traversing apparatus 6 from the state where the pallet 2a is mounted on the pallet traversing apparatus 6 as shown in FIG. explain.
First, the pallet 2a is moved in the following procedure.
(1) As shown in FIG. 3 (a), the pallet traversing device 6 is turned (clockwise in this example), and the pin 6a is deeply inserted into the traversing groove 7a.
(2) As shown in FIG. 3B, the pallet traversing device 6 is turned in the opposite direction (counterclockwise in this example) while maintaining the intrusion. Along with this, movement of the pallet 2a starts.
(3) The movement of the pallet 2a is completed by removing the pin 6a from the traverse groove 7a by turning the pallet traversing device 6 as shown in FIG. 3 (c). Wait for the pallet to move.

Next, when the pallet 2b is moved from the state of FIG. 3D, the pallet traversing device 6 needs to be moved clockwise in order to allow the pins 3c to penetrate deeply into the traversing groove 7b in the pallet 2a.
Here, when the pallet traversing device 6 is swung at the same height as when the pallet 2a is moved, the pin 6a again penetrates deeply into the traversing groove 7a of the pallet 2a, and the pallet 2a is traversed. End up. Therefore, in this case, it is necessary to adjust the height of the cage 4 so as to lower the height of the pallet traversing device 6 so as not to interfere with the pallet 2a.
Specifically, as shown in FIG. 4A, when the pallet traversing device 6 traverses the pallet 2a, the pin 6a needs to be deeply inserted into the traversing groove 7a of the pallet 2a. Although the pallet traversing device 6 is located at the same height, the pallet traversing device 6 is adjusted so that the pallet 2a and the pallet traversing device 6 do not conflict with each other by lowering the height of the pallet traversing device 6 as shown in FIG. Need to do.
Therefore, it is necessary to move the pallet 2a according to the following procedure.
(4) Lower the height of the pallet traversing device 6 as shown in FIG. In Fig.5 (a), the dotted line part of the pallet traversing apparatus 6 is a position before height adjustment, and the continuous line part has shown the position after height adjustment.
(5) As shown in FIGS. 5B and 5C, the pallet traversing device 6 is turned. In the above (1), since the height of the pallet traversing device 6 is adjusted, the pallet traversing device 6 and the pallet 2a can turn without conflict.
(6) As shown in FIG. 5D, after turning the pallet traversing device 6 to a position where it does not conflict with the pallet 2a, the height of the pallet traversing device 6 is returned to the original position.

Finally, the pallet 2b is moved from the state shown in FIG.
(7) As shown in FIG. 6 (a), the pallet traversing device 6 is swung (clockwise in this example), and the pin 6a is inserted deeply into the traversing groove 7b.
(8) As shown in FIG. 6 (b), the pallet traversing device 6 is rotated clockwise while maintaining the intrusion. Along with this, the movement of the pallet 2b starts.
(9) When the pallet 2b is mounted on the pallet traversing device 6 as shown in FIG. 6 (c), the turning is stopped, and as shown in FIG. 6 (d), it waits for the next pallet movement. .

Here, when performing different pallet traversing as described above, it is necessary to adjust the height of the pallet traversing device 6 as shown in (4) to (6) above. The time required for adjusting the height of the pallet traverse device directly affects the loading / unloading time of the vehicle.
In the pallet traversing device 6 described above, after the pallet 2a is moved and before the pallet 2b starts to move (from the state of FIG. 3 (d) through FIGS. 5 (a) to 5 (d)). 6 (a)), it is necessary to turn the pallet traversing device (hereinafter referred to as idle swing) more than half a turn without mounting the pallet. This is because the positions of the pallet traversing grooves 7a and 7b are point-symmetrical with respect to the center point of the pallet traversing device 6, and therefore, in order to traverse the pallet 2b, a detour turning route (FIG. 5). This is because the pin 6a cannot enter the transverse groove 7b as shown in FIG. 6A unless it passes through the clockwise turning route in (a) to (d). For this reason, it is necessary to make a detour in order to traverse the pallet, which also affects the loading / unloading time of the vehicle.

  Accordingly, an object of the present invention is to provide a parking device capable of reducing the time required for height adjustment of the pallet traversing device and the time required for the idling swing.

In order to achieve the above object, according to the present invention, a pallet can be mounted and vertically moved up and down, a plurality of vehicle storage shelves installed on both sides of the cage at intervals in the vertical direction, In a parking apparatus comprising a pallet traversing device for traversing a pallet between the upper surface of the cage and the vehicle storage shelf,
The pallet has a downward traverse groove along the longitudinal direction at one end in the short direction,
The pallet traversing device comprises a swivel unit that swivels to traverse the pallet;
A pin projecting upward at an end of the swivel unit,
Traversing the pallet by turning in a state where the pin is inserted into the traversing groove of the pallet to be transported,
The traversing groove is provided symmetrically with respect to a line passing through the turning center of the turning part and parallel to the longitudinal direction of the pallet.

  According to the present invention, the transverse groove is a position where the insertion starts or ends at a position where a straight line connecting the turning center and the position of the pin is perpendicular to the longitudinal direction of the pallet. Is provided.

According to the present invention described above, when each pallet is stored in a vehicle storage shelf on the same floor, the pallet traverse device is used for traversing in a place that is symmetrical with respect to a line passing through the turning center of the pallet traversing device and parallel to the longitudinal direction of the pallet. A groove is provided.
As a result, the position of the traversing groove on the pallet is symmetrical with respect to the pallet traversing device, so that the pallet traversing device can traverse by making an idle swing of half or less of any pallet on both sides. become.
In addition, as a result of less idling, it is possible to prevent conflict with a pallet that is not traversed during idling rotation. Therefore, it is not necessary to adjust the height of the pallet traversing device, and the time required for this adjustment can be reduced.

Fig.7 (a) is a block diagram of the pallet traversing apparatus in this invention, FIG.7 (b) is a block diagram of the pallet and pallet traversing apparatus in this invention.
In this figure, 12a and 12b are pallets, 13a and 13b are vehicle storage shelves, 14 is a cage, 15 is a hoistway, 16 is a pallet traversing device, 16a is a pin, 16b is a pallet support member, 16c is a turning part, 17a, Reference numeral 17b denotes a transverse groove. It is.
Moreover, about the whole parking apparatus, the same thing as what was described in FIG. 1 is assumed.

The pallet traversing device 16 stores the pallets 12a and 12b that have moved up the hoistway 15 by the cage 14 in a state of being mounted on the pallet traversing device 16 when the swivel unit 16c is swung, in the vehicle storage shelves 13a and 13b. It is. On the contrary, the pallets 12a and 12b stored in the vehicle storage shelves 13a and 13b can be mounted on the pallet traversing device 16.
In this example, the turning portion 16c is an octagon, but other shapes such as a rod shape may be used.

As shown in FIG. 8A, the pin 16a is an upward projection, and in this example, the pin 16a is located at the end (one of the apexes) of the pallet traversing device 16.
On the other hand, the transverse grooves 17a and 17b are provided along the longitudinal direction of the pallets 2a and 2b as shown in FIG. 8B, and as shown in FIG. Can penetrate deeply into the transverse grooves 17a, 17b.
With this configuration, the pallets 2a and 2b can be traversed as the pallet traversing device 16 turns as shown in FIGS.

  The pallet support member 16 b is a member that supports the pallet to be mounted when the pallet is mounted on the pallet traversing device 16.

FIG. 9 is a schematic diagram of the operation of the pallet traversing device when the pallet according to the present invention is mounted on the pallet traversing device.
In the pallet traversing device 16 in the parking apparatus according to the present invention, another pallet 12b is mounted on the pallet traversing device 16 from the state where the pallet 12a is mounted on the pallet traversing device 16 as shown in FIG. The case where it does is demonstrated.
First, the pallet 12a is moved in the following procedure.
(1) As shown in FIG. 9 (a), the pallet traversing device 16 is swung from the state where the pin 16a is deeply penetrated into the traversing groove 17a while maintaining the penetration as shown in FIG. 9 (b). (Counterclockwise in this example). Along with this, the movement of the pallet 12a starts.
(2) After that, as shown in FIG. 9C, when the pin 16a comes to a position where the pin 16a is disengaged from the traversing groove 17a by turning the pallet traversing device 16, the movement of the pallet 12a is completed, and FIG. As shown in the figure, it waits for the next pallet movement.

Next, the pallet 12b is moved from the state shown in FIG.
(3) As shown in FIG. 10 (a), the pallet traversing device 16 is turned (counterclockwise in this example), and the pin 16a is inserted deeply into the traversing groove 17b.
(4) As shown in FIG. 10 (b), the pallet traversing device 16 is continuously turned in a state where the intrusion is maintained. Along with this, the movement of the pallet 12b starts.
(5) As shown in FIG. 10C, when the pallet 12b is mounted on the pallet traversing device 16, the turning is stopped and the movement of the pallet 12b is completed.

In the conventional parking apparatus, from the completion of the movement of the pallet 2a in FIG. 3 to the start of the movement of the next pallet 2b, the state shown in FIG. After the step (d), the state shown in FIG.
Specifically, from the state of FIG. 3 (d) to the state of FIG. 6 (a), in this example, it is necessary to perform the idling rotation of the pallet traversing device 6 by about 225 degrees. Further, in the meantime, it is necessary to lower and raise the height of the pallet traversing device 6 in order to avoid conflict between the pallet 2a and the pallet traversing device 6 that have already been moved.

In contrast to the conventional parking device described above, in the parking device of the present invention, the transverse grooves 17a and 17b in the pallets 12a and 12b are equidistant from each pallet and are parallel to the longitudinal direction of the pallet. It is provided in a place that is line symmetric.
In the parking apparatus of the present invention, when the process from the completion of the movement of the pallet 12a to the start of the movement of the next pallet 12b is considered, by having the traversing grooves 17a and 17b, FIG. In order to change from the state of 9 (d) to the state of FIG. 10 (a), the pallet traversing device 16 may be rotated by about 90 degrees, and the pallet traversing device 16 for avoiding a conflict with the pallet 12a. Height adjustment is also unnecessary.

  Therefore, the parking device according to the present invention can reduce the idling rotation of the pallet traversing device 16 and the height adjustment of the pallet traversing device 16 is unnecessary compared with the conventional parking device. It is possible to reduce the total time required.

  In the parking apparatus of the present invention, the start or release of the pin 16a entering the traversing grooves 17a and 17b is performed, for example, as shown in FIG. The pallet traversing device 16 is designed so that the straight line connecting the two and the longitudinal direction of the pallets 12a, 12b is perpendicular.

This is because, in the process of turning the pallet traversing device 16 from FIG. 9D to the state of FIG. 10A, the pin 16a enters the traversing groove 17b before the state of FIG. 10A. If this happens, the pallet 12b will be pushed once outward (downward in FIG. 10 (a)) while turning from that point to the state shown in FIG. 10 (a). This is because necessary operations are generated.
Therefore, the size of the pallet traversing device 16 is such that when the straight line connecting the pallet traversing device 16 and the center and the pin 16a and the longitudinal direction of the pallets 12a and 12b are orthogonal, the pin 16 is in relation to the traversing grooves 17a and 17b. It is desirable to design the size so that intrusion is started or canceled.

  In addition, this invention is not limited to embodiment mentioned above, Of course, a various change can be added in the range which does not deviate from the summary of this invention.
